grace note, first note

New Lilypond user, four pieces coded, contributed to Mutopia.
I'm using v2.0.1, loaded through Fink on Mac )S 10.2.8.

I have a piano score which I'm trying to code. It begins with a grace
note. The resulting output shows the effect (I'm presuming) of the
grace note not being counted with the main note's value.

I've looked in the archives but haven't found an answer (at least one
which i understand). I've tried a number of things, including adding a
partial measure with spaces at the beginning. The bar line which
accompanies this is aesthetically unappealing. I tried suppressing the
bar line(s) but alignment was disrupted.
